Appiicaun una January as, 192i. serieu No. 439,962.

Be it known that I, DONALD Saskatchewan, `Dominion ot anada, f have invented certain new and useful Improve ments in Grain-Binding Machines, of which the following is a specification.

This invention relates to improvements inV 'ing parts of these machines withoutchange or alteration ofthe latter, and which vwill operate ,in suclivmanner that, after a predetermined number of bundles have been ltermed 4'and delivered onto the bundle carrier, the latter will be automatically dumped to discharge the bundles onto the ground and will then "be returned to initial position.

It is also an object of the y,invention to 'provide mechanism of lthe above character which can be made toidle if it-is desired that the carrier be operated bythe .usual foot lever mechanism, yor if it is-desiredto carryl over one or more bundles for re-.adjusting the dumping points.

Further objects ot'v he invention reside in the novel c(instructionA votthevdiierent parts ot' the mechanism and in their combination with the operating parts ot the machine, to produce an operative attachment.

i ln accomplishing these `and other objects ot the invention, l have provided the improved details oi3 construction, ythe preferred ormsoi which are illustrated inthe accompanying drawings, wherein- Figure l' isa iront elevation of a part of av grain binding machine whereon the 'present mechanism is mounted, showing the main wheel'wliereby the machine parts are driven, the bundle carrier, and dumping mechanism whereby the carrier is controlled. v Figure 2 is aplanview ofthe operating parts et the machine, as shown in Figure l,

Referring more in detail toi'thekseveral views 'of `the drawings,"fwherein like `reiference numeralsdesignate thesame or .like parts-'` 1'- c y l .designates the main, or drivingwheel, o'f a binder whereto the present'mechanism is attached, and Q-aiidB respectively designate front and rearward, longitudinal frame beams between whiclithe Wheel l operates and which arer connected at4 opposite" sides oi? the `wheel by vcross bars rl, shown in ligure 2; the wheel being mounted to suppoi'tthe trame and to drive the `cutting and binding mechanism.` Supported atene side-.of the wheel by means of uprights `5 andf, Figure l, is .arivelevato'n` designated at '7, whereby the grain which falls, after being cut, onto the platform, not shown, is delivered over the wheel and into va receiver d` which extends ldownwardly at'the opposite side of the wheel and wherein the grain is'bound in bun'dles before being deliveredy .ward ends of these shafts.

ward end the shaft has a gear wheel 14 keyedy thereon, Figure 2, driven by a larger gear meshing therewith which is fixed on one end of a shaft 16 mounted at the' rear of the wheel 1 between the cross bars 4 and driven by a chain 17 operating over.`

sprocket wheels 18 and 19 respectively on the shaft and wheel 1. j

Supported in 'frame members, .at a point somewhat above theshaft 1.0, and parallel the-reto .is what'i-s, known as the packer shaft 20, which operates mechanism which forms the bundlesA of grain., y This is driven fromy theshaft 1 0 by a chain belt` 21` operating over sprocket wheels 22 .and 23 at thefrear- At its forward end, the shaft v has driving connection with the shaftA 25 of bundle discharge.

vdrives a relativelylarge gear wheel on' the shaftl25. v

. Beneath the receiver is 'mounted the needle. actuating shaft 31, equipped at one end with a crank arm 32 which is actuated by means of a rod 83 connected wheel 30.

` Briefly stated, the. operation of the binding mechanism is as follows: As the binder is moved forwardly, the main wheel rotates with the periphery of and by means ofthe chain belt 1.7,' rotatesy the shaft 16 to drive, through the connections disclosed, the shafts 10, 2O and 25. The

needle actuating shaft 31 operates in synchronism with mechanism not shown and with the shaft 25 to project the needle designated at 34 to carry the binding twine about the bundles formed in the receiver, and the dischargevarins 35, fixed on the shaft 25, engage the forni-.ed bundles to deliver them onto the bundle carrier arms 9.

The arms 9 ofthe bundle carrier are fixed in ahorizontally mounted shaft 40 supported from the frame at a point below the dis? charge end of the receiverS so as to normally extend horizontally as shown in Figure 1. This shaft 40 is adapted, however, to be partially rotated to tilt the arms `downwardly to discharge the bundles onto the ground. The usual manually controlled 'mechanism for actuating the carrier comprises a dump crank 41 (see Figs. 1 and 4) which is supported in `an inclined manner along the front of the machine within bearings 42 and 43 adjacent its ends. Atits lower end it has adownwardly turned crank arm .44 to which is pivotally fixed the lower end of a link 45 which latter at its upper end, is connected with a rocker arm 46 for rotating` the tube 40, the connection being such that rotation of the dump crank which will swing` the arm 44 upwardly, will permit the tube 40 to rotate to move the arms 9 downward to dump `the bundles therefrom.

At its upper end the dump crank has a forwardly turned' a'rni 47 to which is fixed the forward end of a foot rod 48 that extends toward the rear of the machine to ad jacent a driver"s'seat, as shown in Figure. 3, and at that end is supported by a crank arm 49, and is equipped with a. foot rest 50 against which pressure may be applied to return the carrier after it has been dumped.k

Imakeno claim to theabove mechanism since it is the same as that now in general use, but have described it in a- Oeneral way in order that a clearer uigrderstanding may be had vot the operation of parts which I have applied thereto and which embody the present invention. f

Fixed tothe frame uprightv 5 in such inanner vas .to yextend `ferr.ardly therefrom at a point just above the duanp crank 41, as shown in Figures 1, 2 and 4, is a bracket 51 having a trunnion 51v at its outer end where- 1 on ai ratchet disk 52. is :rotatably mounted. rlhis disk has an arm 5B fixed on its outer face and extended in a radial direction beyond its edge, and which is adapted, as the disk is' rotatably advanced, to engage a trip arm 54 that is fixed to the dump crank 41 to move the said arm upwardly and thereby rotate the trip crank to yactuate thebundle carrier arms to unloading position.

' Fllhe means whereby the disk 52 is rotatably advanced comprises,mechanism including a shaft 55, that is `rotatably supported adjacent the youter side of the wheel land parallel with the shafts 10 and 20. At its forward end the shaftvis provided with a crank arm 5G which is connected by means of a linko? with the pitman 33 so that, as vthe latter isreoiproc-ated by rotation of the wheel 30, the shaft 55 will be partially rovtated back and forth accordingly as the pit-- man ope-rates. j

j Near the forward cud of ther shaft and in alinementhwith ythe disk 52is a crank arm (50, and lixed to the outer endvthereof is `a link` 61 whichhas a folded end portion G2 at the free end overlying the upper edge of lthe ratchet disk 52 and which has ati-ansverse pin 63 through thisend, (see Fig. 5) adapted to engage within 'the notches of the disk so that, with each reciprocation, it ro- 4'tata-bly*advances the disk the distance of the spacing of thenotches, which in the .present device is ninety degrees, requiring sliding lconnection .between the shaft 55j and the crank arm @O which is connected with' parts that have no adjustment forwardly or rearwardly. The character 'of the shaft,

and the manner in which it is shifted isil-l` lustratedbest in Figure 9, wherein 70 and 7l' respectively designate upwardly sloping` beams which area permanent parti ofthe frame of the ma`chine. Fixed to the beam isa bearing 72 through which the rear'- rward end of the 'shaft is slidably'mounted,l

and fixed to the vb'eai'ni is anfarin 7 3 `which extends `forwardly' andhas spaced" apart bearing yoke's 74 and 74 'thereon containing rotatable sleeves T5 and 75 througli'whiclia squared portion '55` of the shaftisslidably extended. The crank arm A(SO is mounted on thissquared portion between the yoke` arms so that it is retained functionally,connected and in. position regardless of shiftingof the shaft 55. In this figure 9, designates a'vv part of the packer frame` which'is s hiftable forwardly andrearwardly as before men?- tioned, and securedr thereto is an' arm 81" vwhich has an end yoke SQextended between collars'83 and 8 3 secured to the shaft 55. so that shifting of the packer frame `will shiftl the'shaft 55 accordingly.

llVhen the bundle carrieris iii receiving' or carrying position, as shown inflfigure l,1tlie crank arm 4LL at thelower end ofthe dump crank. 41 extends downwardly so that its outer end is slightlybeyond the dead center lline with resoect tothe coniiectin0"'linl; 4o'

a l c which operates 'the carrier, and the carrier load tendsfnot'to cause dumping, butto lre-y sist dumping. After the" arm 54 on j the dump crank has been engaged by the arm extending from the vdisk 52, to actuate the dump crank to dump the carrier, this'fcraiikarm44 extends substantially in a horizontal position, and the arm l47 .at its opposite end,

in' Figure 3,

as illustrated in dotted vlines stands substantially vertical.

As soon as a load has been diseliarged from the caiifiei` it is free to be returned to initial position for reciviiig following bundles of grz'iin,` and, tol provide forrautoina-tically returningthe carrier, I have attached a spring 35, as bestshown in Figure '3, at one endto1 the rod 48 adjacent the 'footiest 50and at' its'opposite end tothe frame upright 6. This spring under normal' conditions will by itself return the carrier, `.but in order that the latter will be returned under all conditions, I provide `the rod 4l with a return arin 88 which is fixedy thereto' to ex' tend along` the edge of ,the dislr` 5 2 attlelsi'de opposite the arm 54 and which -is actuated downwardly by the downward travel ofv the arm 53 fixed on the dish'.

The arm 83, at its outer end,'lias asta'r shaped wheel 89 rotatably mounted therein', as shown in liigure 8, with the points 3Q of thewlieel eitendedin such positionr asv to .be
